Magnesia chrome brick manufacturing is generally produced by sintering magnesia and refractory grade chromium ore as raw materials, refractory grains for silicate combination, said magnesia chrome brick, generally refers to the common magnesia-chrome brick, referred to as magnesia chrome brick.
Magnesia chrome brick is mainly used in metallurgical industry, such as building the top of open hearth furnace, electric furnace, refining furnace outside the furnace and various non-ferrous metal smelting furnace. Its quality is divided into ordinary magnesia-chrome brick, directly combined magnesia-chrome brick, semi-combined magnesia-chrome brick, combined magnesia-chrome brick and so on.
The fireproof degree of magnesia chrome brick manufacturing is more than 2000℃, the softening temperature under load is generally above 1550℃, the high temperature volume stability is good, the resistance to rapid cooling and heat is stronger than magnesia-chrome brick.
This series of refractory brick is on the basis of silicate combined magnesia-chrome brick, as far as possible to reduce the impurity content in the raw material, mostly by high temperature firing, firing temperature generally in 1700℃ above. Low impurity content, stable and reliable product quality, welcome to consult and purchase.
Generally speaking, the magnesia chrome brick manufacturing has a wide range of applications. The high- temperature part of the wall of the ultra-high power electric furnace is made of fused magnesia-chrome brick, the high erosion area of the refining furnace outside the furnace is made of magnesia-chrome brick made of synthetic materials, and the high erosion area of the flash melting furnace of non-ferrous metals is made of fused casting magnesia-chrome brick and magnesia-chrome brick made of synthetic materials. In addition, magnesia-chrome brick is also used in cement rotary kiln firing belt and glass kiln heat storage room and other parts.
